SELFPROOF 0605 - RED COLOURSHIFTING (REDSHIFT)

CURRENT PARADIGM

Redshift h
appens when light seen coming from an object that is moving away is proportionately increased in wavelength, or shifted to the red end of the spectrum. More generally, where an observer detects electromagnetic radiation outside the visible spectrum, 'redder' amounts to a technical shorthand for 'increase in electromagnetic wavelength' – which also implies lower frequency and photon energy in accord with, respectively, the wave and quantum theories of light.

COMMENTARY

The wavelengths of photons of extraterrestrial origin gathered here on Planet Earth are always colourshifted from the wavelength at which they first stabilised. The colourshift can be a redshift toward the red end of the spectrum or a blueshift toward the blue. The degree and the direction of the colourshift depends on these two factors:  
  • The rearward gravitypull the photon has experienced during its lifetime versus the forward gravitypull it has experienced.
  • The sum of the energy the photon has absorbed during its lifetime versus the sum of the energy it has ejected.
Thus, interpreting the colourshift of an extraterrestrial photon requires the following to be taken into account:
  • The mass of the emitting object (strictly, the emitting object is likely to be an atom but to keep things simple it can be said to be the galaxy, star, or whatever it is that contains the atom).
  • The direction of emission (photons move at lightspeed so a photon emitted to the fore of a moving object suffers more gravitypull than does one emitted to the rear).
  • The mass of the absorbing object (strictly, the absorbing object is our detector here on Planet Earth but, especially if it is an extragalactic photon, the detector's position within the Milky Way needs to be taken into account. Thus the mass measure needed is the mass of the Milky Way modified by the position of the Earth in one of its spiral arms, some distance out from the galaxy's blackhole).
  • The direction of absorption (photons move at lightspeed so a photon absorbed at the fore of a moving object suffers less gravitypull than does one absorbed at the rear).
  • The distance of the emitting object from the Ucentre at the time of emission.
  • The distance of the absorbing object from the Ucentre at the time of absorption.
  • The altering gravitypull of the Universe as a whole as it expands and thus becomes less dense.
  • The differential colourshifting experienced by a photon during its lifetime from “flyby's” of massive objects (since all objects are moving, the measures of redshift and blueshift resulting from a flyby rarely cancel each other out).
  • The effect of the teelospheres/teelstreams through which photons move during their lifetime (gravitypull strength is an absolute and thus easily predictable if all the factors are known whereas the speed and direction of a teelstream can vary dramatically over a short distance)
A consequence of the above is that most extragalactic objects viewed from Planet Earth are redshifted.
  • The colourshift of a photon, as detected on Planet Earth is the sum of the redshifting and blueshifting it has suffered during its lifetime.
  • The farther an object is from Planet Earth, the more massive it must be for meaningful numbers of its photons to be detectable. Thus they are more likely to be redshifted than blueshifted.
  • Planet Earth is some distance out from the teelcore of a relatively small mass galaxy. Thus the blueshifting of a photon between crossing the Milky Way's gravitysheath interface and reaching Planet Earth is relatively slight and only rarely likely to cancel out the photon's previous redshifting.
  • The Universe is expanding so the distance of most objects from the Ucentre was once less than Planet Earth's current distance from the Ucentre. All photons then emitted will have some degree of redshift by the time they reach Earth. Photons emitted during the early life of the Universe will have a marked redshift.
  • In the early life of the Universe, teelstream speeds were extremely high resulting in the extreme redshifting of newly stabilised photons.



GLOSSARY
  • blueshift:      A photon's wavelength is blueshifted when the photon's mass and energy measures increase from one specified moment to a succeeding specified moment.   
  • colourshift:      The spectral change in a photon's wavelength when the photon's mass and energy measures change from one specified moment to a succeeding specified moment. 
  • gravityshift:     Any change in the mass and energy measures of a blackhole due to its mutual gravitypull with another object. 
  • redshift:     A photon's wavelength is redshifted when the photon's mass and energy measures decrease from one specified moment to a succeeding specified moment.
  • teelstreamshift:     Any change in the mass and energy measures of a blackhole due to its moving from a teelstream with one mass/energy measure to one with another mass/energy measure.
